TRAP FOR BATH-TUBS, SLG.

SPECIFICATION forming part of Letters Patent No. 462,305, dated November3, 189].

Application filed February 18, 1891. Serial No. 881.807. (No model.)

To all whom t may concern.-

Be it known that I, VILLIAM E. DELE- HANTY, a citizen of the UnitedStates, residing at Albany, in the county of Albany and State of NewYork, have invented certain new and useful Improvementsin Traps forBath- Tubs, tbc.; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the iigures ofreference marked thereon, which form a part of this specification.

The object of my invention is to provide a trap for bath-tubs,water-basins, die., that will effectually prevent the escape of sewergasand odors, and that can be set upon the floor of a bath-room, ifdesired, and allow of the bath-tub being set lower or nearer the doorthan is usually done.

In the drawings, Figure I shows a vertical sectional view of one form ofmy trap. Fig. 2 shows a similar view of another form thereof, and Fig. 3shows my trap with its ballvalve raised.

The body of the trap l may be of any coniiguration desired; but I preferit as shown in Fig. l, when set above the floor-line, and as shown inFig. 2 when set below the floorline. The outflow or eduction pipe 2preferably lies above the top surface of the bathvalve 9 when the ballrests on its seat, and this is desirable in order to always preserve awater seal in the trap, as well as to have it sealed by the ball-valve9.

In the trap I, and at its rear side preferably, and as low down in themain chamber as possible, I provide a chamber 10, preferably oblong inconiiguration, and in the top of this chamber l0 I make an opening andform a seat for the ball-valve 9. This charnber l0 is preferablyext-ended out and beyond the main body of the trap l ,as shown at3 inFig. l, forming, preferably, a circular connection tube or pipe, towhich the receiving wastepipes may b'e connected. I prefer to makeconnection therewith by use of a pipe 4, enteredintoconnecting-tube,forming'aslip-jointand rendered water-tight by useof the union 6 and packing 5. Theball-valve 9 is composed of solidrubber or other equivalent substance and has rising from its top a steml2.

In the top of the trap is an opening and a cover therefor, having anextension-tip forming an extended chamber 8, and the stem 12 of theball-Valve 9 enters this chamber 8 and remains therein after the cover 7is set in place, and I prefer said cover to be so set by screwing itinto position, as shown. When that form of my trap shown in Fig. l isused, I stand it on legs or a base 13.

In Fig. 2 I show a form of my trap in which the chamber S is inverted orwholly within the interior of the trap, instead of rising above it, andin this form of my invention the intake-pipe 3 is connected with thelower neck of the trap by an ordinary union, and can be swung around inany direction desired, and in this form I omit the sunken or lowerchamber 10. (Shown in Fig. l.)

In setting the form of trap shown in Fig. l the slip-joint shown at 3and 4 is of great service, as it enables the connection to be made afterthetrap is fastened to the floor and without disturbing it. The openingcovered by cover 7 is longer than the ball-valve 9, sothat the ball maybe removed and inserted therethrough.

The operation is as follows: The water entering pipe 4, Fig. l, fillsthe sunken chamber l0 and lifts the ball-valve 9 oif its seat, the steinl2 rising into chamber 8, and keeping the ball directly over its seatwhen raised. The water then flows through the opening in the top ofchamber 10 and lls the main chamber of the trap and overflows throughexit-pipe 2 into any waste-pipes with which it may be connected, theball-valve 9 remaining suspended directly over its seat during the timethe trap is being iushed, as shown in Fig. 3. When the flow of waterceases, the ball drops back to its seat, and so quickly that it isimpossible for the sunken chamber lO or the main trap to be siphoned,and the top of the sunken chamber being raised above the bottom of thetrap the ballvalve 9 has to sink in only a shallow body. of water, thusrendering its action in regaining its seat quicker and more certain,while the IOO guide-stein l2, sliding up and down in chamber VS, compelsthe ball to move in a direct and undeviating line toward its seat wheniiushing ceases, and away from itin said direct line when forced to risefrom its seat. In Fig. 2 I do away with the sunken chamber; but I employthe stem l2 and inverted chamber 8, and in this form of my trap, whenthe ball rises from its seat, the stem 12, rising in the invertedchamber S, guides the ball in a straight line and directly to and fromits seat.

y When the trap needs cleansing, the cover 7 is removed, the ball-Valvelifted out by its stem, and any refuse removed, and the parts againrestored as before, and the trap is ready for use.

My trap shown in Fig. l is especially useful in connection with baths,wash-tubs, and similar appliances, as its height over all may beless-than ten inches and its size so limited as to occupy but a trilingamount of floorspace, and as it can be made ornamental by nickeling orlacquering it or otherwise beautifying its outer surface it will presenta neat appearance in any room, and it will never be necessary to outaway'oors to set it, as is the Valve therein so that said roof and said'valve will be covered by Waterwhen the trap is not being iiushed, saidvalve having a guide arranged to prevent the water lying over the roofof said chamber keeping the valve from regaining its seat after the traphas been ushed, for the purposes described. In testimony whereof I aflixmy signature in presence of two witnesses.
